hoisting cage and after they are discharged.

from the cage within a mine.

The apparatusalso embodies signal mechanism by which the operator in char e of the cage ma be notified when a loade been dehvered onto the cage in the mine.

Figure I is a view partly in elevation and partly in vertical section of a shaft and drift in a mine with our apparatus. Fig. II is a plan view of the arts shown in Fi I with the cars illustrate in said ure omitted and the flooring of the car trac (partly broken away. Fig. III is an enlar e cross section taken on line III-III, Fig. I with one of the dogs and actuating members therefor carried by the cage shown in elevation. Fig. IV is a top or plan View of the apparatus showing the car tracks at both sides of a pair of mine shafts. Fig. V is an enlar ed vertical cross section taken on line V Fig. IV. Fig. VI is an enlarged elevation of the signal operating members.

A designates a mine shaft andB and B Y drifts that have communication with said may be con shaft. The drifts B and B are connected in the mine asidefrom the shaft to rovide a continuous assageway through w ioh cars dilated to receive substance being mined and carry it to the shaft in order that it may be hoisted with the cars therethrough.

' raised in the shaft A in order that the cars, when in an empty condition, may be'lowered C and C are car tracks-located respectively in the drifts B and B and D are the cars adapted to travel on these tracks.

E is a hoisting cage provided with car receiving rails F and ada ted to be lowered and car has track C, as seen in 6 extends transversely of the track and it has by timbers of the track 0. These to pass onto the track 0 and be received from the track C when in a loaded condition to be elevated to the top .of. the mine.

No invention per se is herein claimed for the parts thus far described.

esi nates rock shafts rotatably mounted in suita le' bearings carried by the cage E andwhich terminate in crank arms 2 at the end of the cage which faces the track 0 when the cag'eis in a lowered osition. We preferably employ two of said rock shafts but an other desirable number of them may be uti ize adapted to move into positions above the cage rails F for the ur oseof serving as stops overhanging sai rails which act to re-' strain a car upon the c e by op osi q the track wheels of the car. ach roc sha t has .fixed to it a counter-balance weight 4 that normally holdsthe dog 3 in a position to obstruct movement of a car from the cage -E' 3 are dogs fixed to the rock shafts and I and which serves to return said dog to an obstructing position after it has been tripped in the manner to be explained.

5 designates a tri lever dis osed in the track 0 in the path 0 travel of t [e cars while moving in thedrift B and adapted to be struck by said cars. This tri lever, which is preferably of V-sha e, has a ee upper end that rejects above t e track 0 adjacent to the shaft A and its lower end is fixed to a rock shaft 6 that is mounted in suitable been ings secured to the su porting timbers of the 1g. I. ,The rockshaft fixed to it a air of trip arms 7 whichproject into the sha t A and are adapted to be engaged by the crank arms 2 of the rock shafts 1 carried by the cage E.

8 designatesforward dogs and 10 rear. dogs slidably fitted in guides 9 and 11 sepported ogs are preferably arranged in pairs as shown and they are ada ted to operate vertically within "the rails of t e track C in such manner that the forward dogs and the rear dogs will be alternately raised and lowered through the 4 due to their presence in front of the car wheels. The two sets pf dogs are disposed sufficiently apart from each other to provide fora car bein restrained upon the track back of'each set'o dogs and the dogs are 0 erated alternately by. means to be descri ed, in'

trackrails to serve'as stops for the cars I) such manner that the forward car may be released to approach the shaft A while aseoond car will be restrained from movement by the rear dogs, after which said rear dogs are lowered to permit forward movement of the second car and the forward dogs are elevated to arrest movement of the second car until such time as it is to continue its course toward the shaft of the mine. The means m for operating the dogs 8 and 10 consist of levers 12 and 13 pivotally supported and connected to the dogs, main operating levers 14 pivotally-supported at 15 and having forward arms 16and rear arms 17, supplemental operating levers 18' pivotally supported at 19and a connecting rod 20 uniting said operating levers and provided with a counterbalance weight 21. The rear arms of the 16 of the main. operating levers. 14 extend into the shaft A sufficiently to provide for their being engaged by the cageE when said cage is lowered in said shaft. When the cage is in an elevated position and being lowered in the shaft the forward ends of the lever arms 16 are held in an elevated position, due to the influence of the counterbalance weight 21 upon said levers and as a consequence the forward dogs 8 are upheld in car restraining position while the rear dogs 10 are maintained in lowered position by virtue of the operating parts connected thereto.

Referring now to the operation of the parts that have been described. It will be I assumed that. the cage E is being lowered "with an empty car thereon and that loaded cars are in position upon the track C as shown in Fig. I and that the forward one of these cars is restrained from movement upon the track 0 by the do s 8. In this connection it is to benoted t at the dogs 8 and 10 would be in positions the reverse of those in which they are shown in said view; i. e., the

.dogs 8 would be in elevated positions and the dogs 10 in lowered positions. As the cage descends to the bottom of the shaftit strikes the projecting ends of the main operating lever arms 16, thereby depressing said arms which at the time of descent of the cage were in elevated positions and elevating the rear arms of the levers so that they will act through the. medium of the connecting rod 20 to move the levers 12 and lower the forward dogs 8 to the, positions shown in Fig. I. The main operating levers also act at the same time to operate the supplemental operating levers 18 and cause t em to operate the levers 13 with the result of effecting upward movement of the rear dogs 10 so that these dogs will be in the positions shown in Fig. I. The parts described will then be in the positions shown in Fig. I. At this time the forward car upon the track 0 is free tomove toward the s aft A and the cage therein and the rear car is .restrainedfrom movement by the rear dogs. The forward car then moves toward the shaft and by striking the free upper end of the trip lever 5 depresses said lever with the result of rotating the rock shaft 6 to which the lever is fixed.

Upon the rotation of the rock'shaft the trip arms 7 carried thereby are moved upwardly beneath the crank arms 2 of the dog suporting rock shaft 1 carried by the cage E.

he trip arms then act upon said crank arms to rotate the rock shafts 1 and move the free upper ends of the dogs 3 from positions in front of the wheels of an empty car D on the cage, thereby freeing said car and permitting it to ride from the cage onto the trackC in the drift B. Immediately after the em ty' car has moved off of the cage the car tfiat is approaching the cage on the track C passes I onto said cage and having passed beyond the trip lever 5, said trip lever is freed so that its action upon therock shafts 1 and the dogs 3 is discontinued. The counter balance weights 4 are therefore permitted to immediately rotate said rock shafts and carry the free ends of the dogs 3 into obstructing positions above the rails on the cage with the result of causing them to hold the loaded car on the cage in order that it may be hoisted thereon. The cage is then hoisted and as it moves upwardly'the main operating levers 14 are freed of restraint, due to the weight of the cagebeing removed from the ends of the lever arms that roject into the mine shaft and the counter-balance weight 21 is permitted to act upon the levers 18, 12 and 13 in a manner to cause the forward dogs 8 to be elevated in the rails of the track 0 and the rear dogs 10 to be lowered in said rails. The next succeeding loaded car is therefore per mitted to advance toward the mine shaft un-' erated as before to permit .the passage of this car onto the cage after the empty car lowered thereon has been discharged.

It is desirable to provide some'means by which cars upon the track C may bekept in a position back of one set of the dogs 8 or 10 without said dogs being operated when the cage E is lowered and raised for other purposes than the hoisting and lowering of cars, such, for instance, as the conveyance ofemloyees to and from the drifts of the mines.

0 therefore provide means' for holding the mechanism by which the dogs 8 and 10 are operated so that the rear dogs may be upheld in the path of travel of the car and be unaffected by the cage. The means shown for this purpose comprises a restraining arm 22 which is loosely fitted to the rock shaft 6 and is adapted to be thrown into enga ement with the forward arm of one of t e main operating levers 14, see Fig. I, and beingcarried by a sleeve that extends to the exterior of the track. C and has fixed to it a hand lever 23 by which the sleeve and re straining arm may be actuated. When these parts are not in use the .hand lever is placed in engagement with a keeper 24 suitably supported and which serves to so hold the hand lever as to prevent interference by the restrainin arm 22 with the operation of the operating ever beneath it.

The parts of our a paratus herein before described are intende to be used in multiple, or in other words, it is intended that two tracks be. utilized in both the drift B and drift B and the parts described associated with each track. It is also intended that two hoisting ca es be employed in the shaft to be raised an lowered alternately and we have shown this multiple arrangement in Fi s. IV and V.

t is desirable to providemeans whereby the empty cars may be brought to rest after they have been discharged from the cages in order that they may be examined and oiled. To provide for the stoppage'of the cars at suchtime we utilize the following mechanism. 25 and 27. are slidable top carr ing bars suitably sup orted beneath the rail; of the track C in t e drift B and which are provided with stop pieces 26 and 28 ada ted to be moved into ositions over the rai s of said tracks in or er that they will be engaged by the wheels of the cars delivered onto the tracks- The stop pieces on each bar are so disposed thereon that the may be moved into positions over the rai s of'one track and be withdrawn from positions over the rails of the other track in each actuation of either bar. The two bars 25 and 26 are adapted to be shifted alternately throu h the medium of operating rods 29 and 30, t e

former of which are provided with crank arms loosely, fitted'to the bar 25 while the 'latter are provided with crank arms loosely fitted to -t e bar 27. Each of the rods 29 and 30 is provided with a crank arm 29 and 30 that 'is positioned in the mine shaft and is adapted to be engaged by aca when said cage descends in the shaft. The last named crank arms are disposed oppositely relative to each other in each instance and wheneach cage descends it acts upon the crank arms to rotate the rods 29 and 30. These rods are so connected to the bars 25 Y and 27 that they will shift said bars alternately and cause the stop pieces of the bars to be carried to and away from the rails of the track C in a manner to provide for a double stoppage of each car after it has been discharged from the cage in order that it may be examined and oiled.

For the purpose of imparting information to the operator of thehoistin machinery at the top of the mine when a oaded car has been delivered onto the cages E we provide the following means: 31 are weighted .arms the inner ends of which are pivotally sup ported at 32 intermediate ,of the tracks (1. These arms are disposed above the trip arms 7 that operate the cage carried rock shafts 1. Each arm 31 has attached to it a flexible connection 33 preferably of rope and said connections are joined to a rope or other pull member 34 that leads to the top of the mine and is adapted to actuate a bell or other signal device. The pull member may be connected to a bell crank 35 that is in turn connected to a rod 36 which has applied to it a take-up spring 37 which serves to pre vent'slack in the pull member and connections 33. Each time that a mine cage descends and the parts of the apparatus are operated to discharge an empty car and permit the transference of a loaded car onto the cage a trip arm 7 beneath the weighted arms 31, acts to elevate one of said weighted arms,

as illustrated in dotted lines, Fig. VI, while it is acting upon'one of the rock shafts 1. Then, as the loaded car passes onto the cage and the trip lever 5 is released, the trip arm 7 descends and permits descent of said weighted arm with the result of causing it to exert a pull upon the connection 33 and the pull member 34 to actuate the signal mechanism at the top of the mine.
